Abstract: 656,420. Sewing-machines. SINGER MANUFACTURING CO. Jan. 5, 1949. No. 347. Convention date, July 30, 1948. [Class 112] Covering needle thread in lock-stitching with eyed needles. In order to permit of the use of a strong check-spring or auxiliary take-up, which, is desirable in a highspeed machine so that it recovers quickly, and a tension device applying the heavy tension which is required in consequence, without causing faulty stitching by reason of excessive pull of the needle thread on the work, a rotary take-up is arranged to exert a frictional pull on the thread to relieve the pull on the work during stitchsetting; the take-up comprises a pair of .revoluble members having different radii of revolution about parallel axes and moving along the thread in a direction away from the tension device at the time of their approach to their stitch-setting positions, the members being rotated with uniform angular velocities at different frequencies. A thread guide is arranged between the take-up and the needle to exert a slight frictional drag on the thread so that there is no slack thread about the needle point when it penetrates the work. In the form shown, the take-up comprises a disc 32, with thread-engaging pin 34, driven at twice the speed of the needle-bar shaft and a disc 33, with two pins 36, driven at the same speed as the needle-bar shaft, both the discs rotating anticlockwise so that the pins move along the thread towards the needle and thus tend to pull the thread in this direction. The tension device and check-spring are shown at 40, 42 respectively. The take-up and thread are shown in full lines in their stitch-setting position, the dotted position being that at the time when the needle enters the work. In the latter position there is a quantity of slack thread, but a guide 44 is placed so that its frictional effect, increased by the weight of the sagging portion T and the greater angle of lap produced by the sag of this portion, keeps the slack above this guide. A threadbreaking device as described in Specification 656,419, is provided at 48.

Patent GB-584601-A (GB)
Title: Production of butadiene
IPC: C07C1/24
Filed: 1945-01-09
Abstract: 1,3-Butadiene is produced by feeding 1,3-butylene glycol into a body of inert organic liquid containing a dehydrating catalyst at 220-350, preferably 260-285 DEG  C., at substantially the rate at which conversion occurs, and separating butadiene from the withdrawn vapours.  Suitable liquids, which may be miscible with the glycol or in which the latter may be slightly soluble, include diphenyl ethane, hexaethyl benzene, benzyl ether, "Dowtherm" (Registered Trade Mark, a mixture of diphenyl and diphenyl oxide), "Nujol" (Registered Trade Mark), various oil fractions, and "cyclic C18 alcohol."  The preferred catalyst is ammonium phosphate including the tri-, di- and mono-ammonium salts or their mixtures or decomposition products formed at the reaction temperatures.  Other catalysts are phosphoric acid, toluene sulphonic acid, ammonium sulphate, mixed calcium and ammonium phosphates, anilin phosphate, acid sodium phosphate, kaolin and clays.  They may be mounted on supports, such as carbon, coke, kaolin, clay, "Filtercel" or "Celite" (Registered Trade Marks).  The ratio of catalyst to heating liquid may be 2 per cent or less if finely divided and up to 50 per cent for larger pieces. A reactor fitted with heating jacket and stirrer contains the catalyst suspended or dissolved in the inert liquid, the glycol being introduced beneath the surface at the rate of reaction.  The vapours produced pass to a reflux condenser for return of any glycol and heating liquid, and are further cooled to condense water and partially reacted glycol or butenol from the butadiene. The condensate is stratified, the upper butenol layer being recycled to the reactor while the upper layer is rectified to remove most of the water from residual butenol which is recycled. The heating liquid and catalyst may be drawn off periodically or continuously for reviving or replacing.  In examples, diammonium phosphate in diphenyl ethane, diammonium phosphate on coke or "Filtercel" in a wash oil, anilin phosphate in a wash oil, and orthophosphoric acid in C18 alcohol are used.

Abstract: 841,398. Finishing fabrics. TRICOTAGEFABRIEKEN VOORHEEN TRANS BEEREN EN ZONEN N.V. Jan. 9, 1958, No. 848/58. Class 42 (1). Apparatus for flattening fabric which has been stitched along its free edges to form a tube, comprises a cylinder on to which the tubular fabric is threaded, driven rollers for subsequently withdrawing the fabric from the cylinders to a spreading device, means for withdrawing the stitching from the fabric before it is treated by the spreading device, and finally, means for folding the fabric. As particularly described, the apparatus comprises two cylinders 8 mounted on a rotatable platform 5 to the end that one can be loaded with the tubular fabric 2 whilst fabric is removed from the second for further treatment. As the fabric is withdrawn from the second cylinder by rollers 14 and 15, the stitching-wire 9 is withdrawn by toothed rollers 10 and 11 to be wound on a spool 12 and the fabric then passes over a spreading device 13 so that it is in flattened form when it reaches the rollers 14 and 15, ready to be folded by a known device 19. The toothed roller 10 is rotatably mounted on one end of a lever 22 pivoted at its mid-point 23 and formed at its other end with a ring 24 through which the wire 9 passes during its passage between the fabric 2a and the rollers 10 and 11. Thus as the tension in the wire changes, the lever pivots about the paint 23 to move the roller 10, thereby adjusting the grip of the rollers on the wire in accordance with the speed at which the fabric is removed from the cylinder 8. The wire also passes over a grid 25, pressure on which counteracts the action of a spring 26 and closes contacts 27 in a circuit controlling the drive to the rollers 10 and 11. Should a break in the wire occur, the contacts are opened by the action of the spring 26 and the drive to the rollers is interrupted.

Abstract: 1436534 Weighing machine BIZERBA-WERKE WILHELM KRAUT KG 9 Jan 1975 [31 Jan 1974] 945/75 Heading G1W A weighing machine comprises a scale support member 1 carrying a plurality of price scales 4, and an optical projecting means settable to project a selected price scale 4 on to a display screen 5 having a reading mark 15, the reading mark 15 being selectively stationary or movable in dependence on the weight measured whereby a single price scale 4 can be used to display prices for two different values of basic price i.e. price/unit weight. Price scales 4 representing basic prices of 1À0, 1À2, 1À4 &c. are used with the mark 15 stationary, mark 15 being provided by the shadow of a stationary plate 17. To use an intermediate basic price such as 1À1, the plate 17 is moved to an inoperative position by an electromagnet 19, and the reading mark 15 is provided by the shadow of a plate 18. Plate 18 is linked to the member 1 so that the reading mark 15 moves a distance determined by the weight measured to compensate for the difference between the basic price of the scale projected, i.e. 1À2 and the basic price desired i.e. 1À1. A selector device 27 having keys 32, 33 adjusts the position of the optical projection system to select the appropriate price scale according to the basic price keyed, and determines the position of plate 17 according to whether plate 17 or plate 18 needs to be utilized to provide the reading mark 15. Plate 18 may be adapted to move with different weight dependent movements so that each price scale 4 may provide a number of basic prices. Alternatively a series of plates 18 having different weight dependent movements may be provided. Instead of two separate plates 17, 18, a single plate may be provided for selectively remaining stationary or moving according to the weight.
